These are so so so beautiful! Can I ask do you darken down your reference photo before you use it? What makes you chose a certain photo? I would love to experiment with white on black for a change because these are incredible!
Thank you! I tweak the caps a bit in PS, yeah. I prefer references where the middle part of the face is in the shadow, like this one, so that there'd be something to draw on both sides, this gives a nice 3D look. But these are hard to come by, so mostly I just go for screencaps where light falls on the profile.
